IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 222,984., dated December 30, 1879; application filed July 3, 1879.

. enee being had to the accompanying drawings, where- Figure 1 is a side view, showm g the face of the share and mold-board. Fig. 2 is a side View, showing the opposite side. Fig. 3 is a bottom view. Fig. 4 is a rear view.

The invention relates to that class of plows which have, as distinct parts, a mold-board,

- share, and land-side.

The object and purpose of the invention, is

twofold: first, to obviate the necessity of the appearance of bolts or holes therefor on the working-faces of these parts; and, second, to furnish each of such parts with a substantially lateral support from each of the other parts.

- The invention consists in providing the mold-board and share, each of them, with a flange upon the back side, made integral therewith, and in providing the land-side with a flange upon the back side, made integral therewith, which extends to and is bolted to the flanges of the mold-board and share, thelandside flange forming a base for the attachment of the other flanges.

The letter 0. denotes the mold-board, hearing the flange a, integral therewith." I) denotes the share, bearing the flange b, integral therewith. 0 denotes the land-side, bearing the flange-base c, integral therewith, to which the flanges a b fit and are secured by bolts or the like.

The letter (Z denotes the standard, attached at its foot to a wing projecting from the landside, and, higher up, to a wing projecting from the mold-board.

The letter 0 denotes a leaf on the moldboard, designed to be used for the attachment of a plow-handle, the other handle usually starting from the beam.

A modification, perhaps too obvious to need mention, is that the short downwardly-extending leaf, which forms a part of the base-flange, may be dispensed with and the flange b fitted to the remaining leaf.

I claim as my invention The mold-board a, with its flange a, the share b, with its flange b, and the land-side c, with its base-flange 0, extending and secured to the other flanges, all combined, substantially as shown and described.

LUKE OHAPMAN.
